-- Notes:  
-- This testbench has been automatically generated using types std_logic and 
-- std_logic_vector for the ports of the unit under test.  Xilinx recommends 
-- that these types always be used for the top-level I/O of a design in order 
-- to guarantee that the testbench will bind correctly to the post-implementation  
-- simulation model.
